OK OK boys... yes I know 2n2222's are wonderful and plentiful, but I
have a heap of geriatric bipolar power transistor I thought it might be worth experimenting with:- 2n3055 (three) 2n3054 (four) 2n3739 (two) 2n4800 (one) Sony D292 U38 (two) Sony 2sc895 (one) I thought if you can get anything up to 500mW with a general purpose NPN, then what can you get out of an old power transistor? I also have a load of BD139 medium-power transistors...? Any thoughts? In addition, I am still looking for the COMPONENT LAYOUT for the PCB for a QRP transmitter called "little joe" described in 9-81 in QST. I am not looking for just the circuit diagram but where the parts GO on the PCB! Stephen G7VFY 07956-544202 |
